In a bid for leading-man stardom, Almost Famous' Lee sheds his sly, offbeat charm to play the kind of humiliation-prone boob Ben Stiller can now do blindfolded. Engaged to schoolmarmish Karen (Selma Blair), Lee's pasty Paul wakes up in bed post-bachelor party with a kooky tiki dancer (Stiles). Lee stumbles through a string of increasingly senseless scenarios (diarrhea! crabs! drug arrest!), while Stiles does her eye-rolling best with a woefully cliche-riddled script. Add to that a totally implausible ending, and it's just A Bad Thing.
